To all w/tom 'ift 71mg conceive:

Be it known that I, FEED J. ViEwEG, a citizen of the United States ofAmerica, and

a resident of Plainfield, Union county, N ew.

Jersey, have invented certain new and useful Improvements in Locks, ofwhich the following is a specification.

My invention relates generally to locks, and has more particularreference to the novel construction and arrangement of parts 'which willbe more fully described hereinafter.

In my patent of March 21, 1905, No. 785,132, I show and claim a keylesslock, operative at all times from the inside of the door and having'means operable from the outside for rendering the latch mechanismoperative or inoperative from the outside. IVhen on the inside of thedoor, it is possible to render the latch mechanism inoperative but notoperative as to the outside.

In my patent of Nov. 28th, 1905, No.

805,687 is shown a keyless lock which can berendered operative orinoperative as to either side from either side of the door. The latchmechanism, however, is always locked or unlocked as to both sides of thedoor at any time. In other words, the latch mechanism cannot beindependently operated on either side of the door.

In this application, I have shown a keyless lock, operative at all timesfrom the inside of the door, provided with means operable from theoutside of the door for rendering the latch mechanism operative orinoperative from that side as desired, and means operable from theinside for rendering the latch mechanism not only inoperative but alsooperative from the outside. I pause here to remark that when I refer tothe insideH or outside of the door either in the specification orclaims, I do not mean to use an expression of limitation, but adoptthese Words merely for convenience in phraseology.

In the prior locks referred te, I employed for' the ends sought a collarwith a labyrinth of grooves, and a pin engaging therein, the collar andpin being relatively movable. I have found it more convenient inpractice to use a disk than a collar, and this application shows thespecific means by which I adapt the disk to my keyless lock. Again, inthese prior locks, the aim was to connect the parts of a two partspindle, one part of which was in permanent engagement with the latchmechanism, or to move some member which connected the spindle direct tothe same.

This has proved unnecessary, as I find it as satisfactory in practice toutilize the combination member itself, as the collar or disk, to actuatethe latch mechanism through suitable connections. For determiningtherelative movement of the collar and pin in these former locks, Iemployed means located outside of the casing of the lock. In thisinstance, I use the combination member to unravel its own labyrinth tothe initiated,-- that is, to indicate through the sense of touch thepassage of the pin through its labyrinth. of grooves.

In attaining the above general ends, I have made specific improvementswhich will appear as the speci'lication proceeds.

The accompanying drawings illustrate my invention, and I have used likenumerals to designate like parts in the several views. Any mechanicskilled in this art, can readily suggest rearrangement or di'lferentconstruction of parts, and I therefore do not limit myself to thespecific arrangement or structures shown. The spirit of my inventionwill be limited only by the claims.

In the drawings: Figure 1 is a longitudinal sectional view taken on theline 1 1 of Fig. 2. Fig. 2 is a sectional view taken on line 2-2 ofFig. 1. For convenience, in showing its relation to the other parts, thedisk, which is in front, is shown in dotted lines.A Fig. 3 is a viewsimilar to Fig. 2, looking from the other side of the door with thelatch withdrawn. Fig. 4l is a plan view showing the disk with itslabyrinth of grooves and its edges indented. Fig. 5 is a detail viewpartly in section showing the inside knob and connections. Fig, 6 is aldetail end view of the knurl piece shown in Fig. 5 in cross section.

In the drawings are shown my lock arranged in the stile l of the door.The latch mechanism is contained in the casing 2 provided with the usualface plate 3 through an aperture 4 in which the latch bolt 5 operates.

The latch mechanismis here shown .in conventional form and consfstsessentially of the yoke 6 attached to the latch bolt and connected tothe latch arms 7 and 8 moving on l the guides 9 and 10 and provided attheir rear l ends with the bent portions 1.1 and 12 respecl tively. Thesprings 13 and 14 act on the i yoke to keep the bolt thrust outwardly ori normally in its locked position. The roll back 15 engages with thebent portions of the latch arms in a well known manner. l Properlysecured in position by the es- IOO cutcheon plates 16 and 17 is a twopart spindle, the ends of which are adapted to engage with each other.The outer spindle member is designated by the number 18, the innerspindle member by 19, and the knobs 20 and 21 serve to Ioperate therespective spindle members. As previously stated, l use the terms insideand outside for convenience only, since the parts could of course bereversed and the spindle members applied to the opposite side of thedoor from that shown in the drawings.

The inner spindle member is at all times in operative relation to thelatch mechanism by means of the key 22 formed on its circumference andin permanent engagement with the keyway 23 formed in the collarextension 24 of the roll back.

The outer spindle member is kept in position by means of the lugs 25 andat its inner end is chambered at 26, the walls of the chambered portion26 being angular in shape to engage with an angular recess formed in themovable member 27, here shown as a disk and whose function will now bedescribed.

l have aimed to supply for the outer spindle member means entirelyindependent of the inner spindle member adapted to bring the outerspindle member into or out of operative relation to the latch mechanism.lVhile this may be accomplished in various ways, l have here attained mypurpose by providing a movable member and means whereby the movablemember is capable of actuating the latch mechanism through properconnecting mechanism at a predetermined point in its movement. Themovable member is shown in the form of a disk having its face providedwith a labyrinth of grooves 2S and the connecting mechanism ispreferably in the form of a spring link 29 pivoted to an arm 30 of theroll back. On the side of the link toward the grooves is a pin 30ZLadapted to engage with the grooves and to be guided through them by themovement of the disk until the latter is capable of acting upon the pinto actuate the latch mechanism. To enable the latch mechanism to beoperated by the rotation of the disk, l provide yin the grooves ashoulder 31 to which the pin of the link is led when the disk is rotatedor turned a variable predetermined number of times and a variablepredetermined distance in opposite directions. As will be readilyunderstood from an inspection of Fig. 3, when the pin is in engagementwith this shoulder, the further movement of the disk acts on the pin andlink to actuate the roll back and thereby withdraw the latch bolt.

It is highly desirable to so form the grooves that the pin will beprevented from taking the right course in the grooves when thecombination has been improperly operated. Means for accomplishing thisresult may take various forms. l have here formed in the groovesinclines 33 and so fashioned the grooves on the faceof the disk thatthey all lead the pin, when the combination is improperly operated, intothe groove 34 in which groove it is impossible for the disk andconnections to operate the latch mechanism. To counteract any tendencyof the inclines of the grooves to throw the pin out from the grooves, lhave provided on the opposite side of the link, aprojection 35contacting with the casing and thereby 1keeping the pin securely in thegrooves as it passes through them` -lt is further necessary, when thepin comes into engagement with the shoulder in the grooves and therotation of the disk acts upon it to withdraw'the latch mechanism, thatmeans be provided for keeping the pin securely against the shoulder.Therefore, l have provided on the casing, a lug 36 onto which theprojection on the link slides when it reaches the proper point, therebyholding the pin up to its work against the shoulder.

TWhen the pin of the link is in engagement with the shoulder in thegrooves and the latch mechanism therefore operable by the rotation ofthe disk, means should beprovided readily throwing the pin out ofengagement with the shoulder in order to make the latch mechanisminoperative as to the outside. For this purpose l have formed on thecasing a cam 37 which will move the pin along the face of the shoulderwhen an eXtra pressure is exerted on the disk until the pin slips by thecorner of the shoulder and through the action of the latch springs isswept through the grooveV 38 into the groove 34.

The pin, in passing out of engagement with the shoulder, must impart aneXtra inward motion to the latch bolt equal to the longitudinal movementof the pin, and provision must therefore be made to retract the latchbolt such necessary distance within the face plate. The pin, as it slipsoff the high portion of the tapers in the grooves has a tendency toproduce a slight click sufficient to enable picking of the lock with theaid of a stethoscope. l therefore provide a safety means in the shape ofa duplicate spring link, pin and projection numbered 39, 42 and 43respectively, the link being pivoted at to post 4l formed on the casing.rlhis arrangement is a duplicate of the active link 29 and pin 30, andas it travels over the same passage or tapers, will produce the sameclick and might be called a blind pin or misleader as its only missionis to produce a similar sound to the active pin so that if it isattempted to pick the lock by sound, it will mislead the operator.

ln my prior inventions referred to in the lirst part of thespecification, l have provided means outside of the casing of the lockfor ascertaining the proper operation of the combination,-that is, thepassage of the pin IOO IIO

through the grooves to such a point that the latch mechanism. becomesoperative. I have here done away with this auxiliary index or guide, andemploy the combination member itself to indicate to the initiated theproper course of the pin through the grooves. This is accomplished byforming in the edge of the disk a series of indents 44 corresponding tothe divisions of the labyrinth of grooves. A pawl 45 is adapted toengage with these indents informing the operator by the sense of touchwhen it has engaged with the same. Means should be provided for forcingthe pawl into engagement with the indents as they present themselves.The means which I prefer are shown in Fig. 3 where I have mounted thepawl on the post 46 formed in the casing and provided the pawl with thelever 47 adapted to throw the pawl into the indents. A spring should beprovided for actuating the lever to throw the pawl into the indents. Inthis case I have utilized the latch springs for this purpose as will beunderstood from an inspection of Fig. 3.

It may be found desirable to bring the spindle members into engagementand to keep them united for the purpose of using the lock as a daylatch. Furthermore, it may be desired when on the inside of the door torender the latch mechanism operative from the outside of the door aswell as inoperative. That is, assuming the outer spindle member to beout of operative relation to the latch mechanism, it may be founddesirable when on the inside of the door, to render the latch mechanismoperative or inoperative from the outside without moving the combinationmember. To that end, the two part spindle has its ends adapted to engagewith each other, and means are provided for holding the parts of thespindle normally out of engagement, while other means arev adapted tohold them united when the ends are brought into engagement. Theengagement of the parts of the spindle is attained by forming a recess48 in the inner end of the outer spindle, While in a recessed. portion49 of the inner spindle part and seated on the spring 5() therein is themember 5].. Both the recess on the outer spindle and thelast mentionedmember will of course preferably be angular in shape. The spring 50serves to throw the member quickly into engagement with the recess whenthe latter and the member are in alinement. Acting against the insideknob to keep the spindle parts normally out of engagement, is the springl52, here shown seated on the knurl piece 53. The latter is provided onits inner end with the chambered recess in which is formed the groove 55and extending through the inner spindle member and resting in saidgroove when the spindle parts are 'out of engagement is the pin 56.

Vhen it is desired to unite the spindle parts, the inner knob is pushedin against the action of spring 52 and the knurl piece is turned to keepthe knob in its inward position. The member 51 may not be in alinementwith recess 48 at the time the inner knob is pushed in, thus forcing itinto the inner spindle and causing a compression on spring 50 and this sring will then snap it into engagement with tlie recess when thealinement is made; that is, immediately after rotating either knob ashort distance. Key 22 is in slot 66 provided in member 5l so as tolimit movement of the member and keep it out of engagement with recess48 when the inner knob is in its outward position.

In pushing the knob 21 inward, the pin 56 is forced from the groove 55in the knurl piece, and by turning the latter the pin rests on theshoulders 57 on each side of the groove and the spindle parts arethereby held in engagement with the latch mechanism which is thenoperative from the outside of the door through the inner spindle member,whose key is always in engagement with the keyway of the roll back.W'hen, now, it is desired to throw the outer spindle out of operativerelation to the latch mechanism, the knurl piece is turned 'until thegroove comes under the pin 56 when the action of the spring 52 willforce the member 5l out of engagement with the recess 48. If thecombination member has, during this process of uniting and disunitingthe spindle members, been out of operative relation to the latchmechanism, the latter will then be left inoperative from the outsideexcept by manipulating the combination.

The operation of the lock is as follows: Assuming the latch mechanisminoperative from the outside, the indexes 58 and 59 on the knob 2() andescutcheon 1.7 respectively, are brought into alinement when the pinwill be located at 60 in the labyrinth of grooves. Then by rotating thedisk in opposite directions, the pin is guided through the grooves tothe shoulder when the further rotation of the disk acts on the pin toretract the bolt and the lock is open from the outside. Then it isdesired toloek the door from the outside, the pin may be returnedthrough the labyrinth to the groove 34; or the disk may befurtherrotated., the cam 37 pushing the pin over the shoulder when thelatch spring will cause it to go through the groove 3S to the groove 34thus throwing it out of connection with the latch mechanism. Then it isdesired to have the door open at all times, as for use in the daytime,the bolt is converted into a day latch in the manner previouslydescribed. The grooves of the disk can. be varied either in length ornumber or divisions, the combination. thereby being changeable asdesired. In this case I have shown a disk having its grooves formed intotwelve divisions as indicated by the notches on the disk best seen inFigs. 3 and 4 and the combi- IOO lIO

nation is 3, 9, 3. e. the pin being at the starting point is led throughthe grooves to 6l, where, if the disk be turned too far, the pin slipsover the tapered portion 62 and passes into the groove 34, it beingimpossible to return it to 61 without bringing'it back to the startingpoint. From 6l the pin is moved to 63, then to 64, when the motion beingreversed, the pin is brought to the shoulder at 65 and the latchmechanism is operative tromthe outside At each point where the directionof rotation should be changed, the pin is prevented by the inclines fromtaking the right course if moved too far, and the combination thereforeimproperlyY operated. The combination of grooves can of course bechanged and the disk can therefore be move d a variable predeterminednumber ot times and a variable predetermined distance in oppositedirections to bring the pin to the shoulder. Of course cams havingdifferent combinations can be readily substituted. The rst number of thecombination can be changed by removing the outer knob with the spindleand replacing it, merelj,T changing its position in relation to theangular hole in the combination disk. In case the combination is on, itcan be thrown out from the inside by pressing the inner knob and spindleinto connection with the outer one and upon rotating it, the pin will beforced out of connection with the latch mechanism, as previouslydescribed.

It will be seen 'from an inspection ot Fig. l that the passages 62, 62aand b constitute misleading` passages, whereby when the cam disk isimproperlyv operated in either direction the link or other member willbe caused toI take a course which will le ad it to the starting grooveSe in less than one revolution or the disk without reversing the motion.
